If, for example, a dowel is welded into a blind hole made perpendicular to the side surface of a wooden part (perpendicular to the direction of the fibers), the dowel material penetrates into the wood, particularly in the area of the end of the blind hole and particularly transversely to the blind hole, as a result of which the anchor is properly anchored. The form of such anchoring that can be achieved obviously also depends in particular on the design of the dowel tip.

  • Energy direction transmitters can be applied to lacquer layers by means of screen printing dots or introduced into film material (process variant according to FIG. 2) by appropriate structuring. It turns out that specially applied energy direction transmitters are usually not necessary when connecting lacquered wooden parts because the lacquer layer, due to its own structure and due to the roughness of the lacquered wood surface, has sufficient unevenness that can take over the function of the energy direction transmitter .
  • FIG. 12 also shows schematically (section through the parts 10 and 11 to be connected before the connection and after the connection) the attachment of an end strip 10 made of a thermoplastic on an end face of a fiberboard 11, the surface of the end strip which is connected to the chip - Plate is to be connected, has energy directors in the form of longitudinal increases.

Abstract

Des éléments (A, B), constitués au moins en partie par du bois ou par des matériaux analogues au bois, sont assemblés en insérant au moins une couche thermoplastique (L) entre les zones des surfaces à assembler, puis en soumettant lesdites zones à une excitation de nature mécanique, par exemple, au moyen d'ultrasons. La couche thermoplastique utilisée est une couche de vernis incolore ou coloré (L) jouant le rôle d'un revêtement scellable dans les zones des surfaces à assembler, et un rôle de protection et/ou de coloration dans les autres zones. On utilise, dans le procédé de l'invention, comme produit approprié, des vernis de type connu renfermant un composant thermoplastique, par exemple, des vernis acryliques. Un soudage par friction ou orbital peut être utilisé à la place d'un soudage aux ultrasons.
